The new object, which was also found at V = 18.0 in six stacked 90-s images taken at La Sagra with a 0.40-m telescope on July 16.091, is located at R.A. = 21h50m54s.34, Decl. = -17d46'09".4 (equinox 2000.0), which is 6" west and 5" north of the nucleus of the galaxy PGC 190539. Nothing is present on a Digitized Sky Survey image from 1995 June 5 (limiting red mag 22).
